Abstract

The invention relates to a dormant solder iron bracket. The solder iron bracket can save about 50 percent of electric energy by putting a solder iron on the solder iron bracket. When the solder iron is electrified and put on the solder iron bracket, a trigger triode is conducted by the induction electromotive force of the solder iron, then a storage capacitor of a trigger diode has short circuit,and the current cannot pass through trigger diode, so the conduction of a controllable silicon cannot be triggered to achieve the aim of voltage separation and energy saving.

Description

Dormant solder iron bracket

Affiliated technical field

The present invention is mainly used in flatiron in the idle process of energising, plays the use power that reduces flatiron, the effect that keeps flatiron temperature simultaneously.

Background technology

Common solder iron bracket only plays the effect of placing flatiron, but can not reduce power consumption when flatiron is idle, has not only wasted electric energy but also can make the solder horn oxidation.

Summary of the invention

For flatiron can be cut down the consumption of energy in idle, guarantee temperature, flatiron can total power be powered in use.

Because the power supply that the common electrical flatiron uses is alternating current 220V, so utilize the unidirectional conduction of diode, when the positive half cycle of power supply, it is charged to an electric capacity, after electric capacity reaches certain energy storage, reach the trigger voltage of diac, the diac conducting, make its corresponding controllable silicon conducting, positive half cycle current is finished the loop, when secondary half cycle, directly get back to power supply, finish the loop by another diode.

Because the essence of flatiron itself is the spiral heating silk, can be regarded as inductance coil, so can produce certain induced electromotive force, when flatiron is idle, flatiron is put on the Iron Stand (metal), when the positive half cycle of alternating current, utilizes the induced electromotive force that himself produces, trigger triode, triode is in magnifying state, makes it the storage capacitor short circuit with diac, does not reach the conducting voltage of diac, and then making the controllable silicon conducting that is not triggered, electric current is directly finished the loop through resistance.

The invention has the beneficial effects as follows, fully heat during work, and when flatiron is idle, not only kept flatiron temperature that prevent the solder horn oxidation again, topmost effect is to reduce the flatiron energy consumption.

The specific embodiment

Fig. 1 is the complete circuit of circuit for this reason, and diode A/B (1) (2) has interchange to be selected to function, finishes the control respectively of alternating current positive-negative half-cycle.

In Fig. 2, triode (7) is in cut-off state, electric current is given storage capacitor (4) charging of diac through resistance (3), thereby reach the conducting voltage of diac (5), after diac (5) conducting, and then triggering controllable silicon (6) conducting, electric current is got back to power cathode through controllable silicon (6).

In Fig. 3, electric current is directly finished the loop through diode B (2).

In Fig. 4, flatiron (12) is put on the solder iron bracket (10), the induced electromotive force that utilizes flatiron itself to be produced, make triode (7) be in magnifying state, triode (7) conducting, make storage capacitor (4) short circuit of diac (5), do not reach the conducting voltage of diac (5), then controllable silicon (6) can't conducting, according to rating formula P=U^2/R, and the internal resistance of common flatiron is generally less than 1.5K, and the resistance that be connected in series this moment is 300K, be far longer than the flatiron internal resistance, the power that it consumed is P=U^2/ (R1+R2), so whole flatiron circuit is (R1+R2)/R1 ≈ 200 in its work with being put in the power ratio that is produced before and after the Iron Stand, promptly when flatiron is positioned on the Iron Stand, its power that is produced at the positive half cycle of power supply be less than its when using the power that produces 1/200, because the use power of common flatiron is generally below 100W, therefore when flatiron is positioned on the Iron Stand, entire circuit can be ignored at the electric energy that the positive half cycle of power supply produces, so the power that entire circuit is produced when idle be at ordinary times 1/2, play certain energy-conserving action.
